Pin Header Connector

Pin Header Connector is a basic electronic connection device composed of single or multiple rows of metal pins and plastic bases. It is usually used in conjunction with corresponding sockets (such as sockets and IDC connectors) to achieve electrical connections between circuit boards (PCBs) or between circuit boards and cables. Its core advantages lie in its simple structure, low cost, and convenient installation, which are widely used in low to medium complexity electronic devices.

Core Functions and Features

Electrical Performance

Signal transmission: Supports low-frequency signals (≤ 100MHz), suitable for control signal and power transmission.

Current carrying capacity: Single pin maximum current of 1-3A (depending on material and size), meeting conventional power supply requirements.

Machine Design

Standardization of spacing: Common spacing is 2.54mm (0.1 inch) and 1.27mm (high-density type).

Plug and unplug lifespan: typical value 500-1000 times (gold-plated pins can reach 3000 times).

Installation method: Through Hole Welding (THT) or Surface Mount Technology (SMT), compatible with automated production.

Materials and Reliability

Pin material: phosphor bronze (excellent conductivity), brass (low cost), surface gold-plated/tinned to prevent oxidation.

Base material: PA (nylon, high temperature resistant), PBT (chemical resistant).

Environmental tolerance: working temperature -40 ℃~+105 ℃, some models support IP20 dust prevention.

Industry Trends and Challenges

Market Demand

Miniaturization: The demand for high-density connections is driving the popularity of 1.0mm pitch products.

Cost sensitive: The consumer electronics industry has a strong demand for low-cost, high-volume solutions.

Technical Upgrade Direction

High frequency expansion: Optimized pin design to support higher frequency signals (such as 10Gbps differential signals).

Environmental resistance: Develop high-temperature and corrosion-resistant materials (such as LCP base).

Industry Standards and Compliance

Safety certification: Must comply with UL, IEC 60664 (insulation performance) and other standards.

Environmental requirements: RoHS and REACH restrict the use of hazardous substances.

Summary and Suggestions

Product Positioning

As a basic connection solution, the needle socket connector is irreplaceable in low-cost and standardized scenarios, but it needs to compete with high-end connectors such as board to board and FPC to form differentiation.
